It’s the most dreaded of days — Monday. Lighten things up with some free games: we’ve got Knight’s Odyssey, which lets you get some aggression out by hacking up medieval enemies; Fling Pong, a game that uses real images from the Hubble Telescope to make its ping-pong game graphics; and Atomic Ball, an addictive brick-breaker with 60 levels to play through. Download them all below and enjoy.

Knight’s Odyssey (iPhone, iPad) Free (was $0.99)

Take the field of battle in Knight’s Odyssey, a side-scrolling brawler in which your mission is to vanquish foes by hacking them apart and avoiding death yourself. As you move forward, you’ll encounter more and more enemies of different types. Take them on by quickly slicing away with your sword or using unlockable magic spells, but be careful not to fall victim to their swords, spears, magic and explosive catapult ordinance.

As you continually hack through enemies, your character will become stronger and gain levels that can be used to unlock magic spells for use in battle. You’ll be able to put all manner of hurt on enemies, gaining the ability to do things like freeze them in place or set them on fire. Knight’s Odyssey isn’t extremely complex, but for free, it’s not a bad casual experience with which to spend a few minutes.

Fling Pong – The Planets (iPhone, iPad) Free (was $0.99)

It’s ping-pong, but with planets — great graphics and beautiful backgrounds are on-hand for Fling Pong, which lets you play a little table tennis with celestial bodies. The game is played with an unlimited number of balls that you need to bounce toward a wall in front of you, which has planets as targets that you need to hit in order to score points.

Challenges are divided up into 32 different stages in Fling Pong, and the game has OpenFeint support, which posts your scores to online leaderboards and lets you earn achievements. Fling Pongs graphics are based on the real planets, too — the game was built using images from the Hubble Space Telescope.

Atomic Ball (iPhone, iPad) Free (was $0.99)

There are bricks to be broken in Atomic Ball, a game that uses some fairly classic gameplay to its advantage by letting you bounce the titular nuclear orb off a paddle you control with your device’s touchscreen. Blast through 60 levels of brickbreaking action, with something like 30 different power-ups to change up play and give you an edge.

High scores are the name of the game in Atomic Ball, which tracks them both on local lists and online leaderboards care of Game Center. It also packs 20 achievements and six graphical themes that you can switch between while you play.
